CLEARANCE OF BROMINATED DIBENZO-P-DIOXINS AND DIBENZOFURANS AFTER A SINGLE INTERPERITONEAL ADMINISTRATION IN COMPARISON WITH 2,3,7,8－TETRACHLORODIBENZO-P-DIOXIN IN MALE WISTAR RAT-A PRELIMINARY RESULT

摘要

Introduction Polybrominated dibenzo-p-dioxins and dibenzofurans (PBDD/F congeners) are unintentionally produced during various combustion processes of plastics, textiles and other materials containing brominated flame retardants (BFRs) or present as contaminants in technical mixtures of BFRs. Workplace air concentrations of tetra-BDDs and tetra-BDFs measured during the extruder production and injection molding of polybutyleneterephthalate polymer blended with the grass fiber, Sb2O3 and decabromodiphenylether (DBDPE) were reported to be 2 and 34 ng/m, respectively.
